PAINTING APPARATUS.

Specification of Letters Patent.

Patented June 1, 1920.

Application filed May 22, 1919. Serial No. 299,006.

To all whom it may concern:

Be it known that I, ROBERT HAINSEY, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in a Painting Apparatus, of which the following is a specification.

The invention relates to a painting apparatus, and more particularly to the class of fountain painting apparatus. i

The primary object of the invention is the provision of an apparatus of this character wherein the same is readily portable and in the use thereof a continuous flow of paint will be supplied to the brush, thus facilitating the painting or coating operation and obviating the dipping of the brush into a paint pot or receptacle. 7

Another object of the invention is the provision of an apparatus of this character wherein the reservoir receives air under compression to cause proper feeding of the paint to the brush when in use.

With these'and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the accompanying drawing:

The figure is an elevation of the paint reservoir and adjunct parts of the apparatus constructed in accordance with the invention, the wall of the reservoir being broken away.

Referring to the drawing in detail, 1 designates a reservoir or supply tank which is of substantially cylindrical shape, having a plurality of legs 2 at the bottom thereof. The bottom 3 of the reservoir or tank is of substantially conical formation and is arranged within the said reservoir or tank, the bottom being formed concentrically thereof with an outlet opening from which leads a discharge conduit 4:, the conduit being fitted with a valve, preferably of the turn-plug type as at 5, and is located adj acent to the outer extremity of said conduit. The outer extremity of the conduit is formed with a nipple 6 for the detachable connection therewith of a flexible tubing 7 which may be of any desirable length. The valve 5 is hand operable and regulates the passage of paint into the tubing 7. Interiorly of the tank or reservoir 1 spaced from the top thereof is an annular baffle ring 8 which serves to prevent the splashing of the paint within said reservoir ortank and the resultant shifting or varying of the weight. A suitable opening is formed within the top of the reservoir or tank 1 and is bordered by an externally screw threaded nipple in which is detachably engaged a-complementary threaded closure cap 9. On the removal of the cap 9,.paint can be introduced into the reservoir or tank as will be clearly obvious.

To permit the compressingof air within the reservoir or tank 1 whereby the paint or other coating fluid contained therein may be placed under pressure, there is secured to one side of'said reservoir or tank an air compressing pump 10, the metal straps 11 being trained about the cylinder ofsaid pump and are fixed at 12 to the tank or reservoir so as to 'unite the said reservoir or tank and pump together. Extending from the bottom of the cylinderof the pump 10 is a tubing 13 which engages with a coupling combined with a valve casing 14 formed on the top of the reservoir or tank 1 and within said casing is a suitable check valve, whereby the air within the reservoir will be prevented. from passing upwardly into the tubing 13 and then being drawn into the pump 10 upon the up-stroke of the piston working within the cylinder thereof. Located at the point of the valve casing 14 and depending within the reservoir or tank 1 is a funnel-shaped member 15 which forms a guard, preventing contact of the paint with the valve.

To permit the carriage of the reservoir or tank 1 by an operator, there is arranged at diametrically opposite sides of said reservoir or tank, cleats 16, and likewise mounted upon the top of the tank or reservoir are similar cleats 17 Secured to the cleats 17 are the ends of adjustable straps 18 which aretrained through the cleats 16 to slide freely therethrough, the free end of one strap being fitted with a buckle while the free end of the other strap is adapted to adjustably engage in the buckle, and in the use of these straps the same can encircle the body of an operator, for the mounting of the tank or reservoir to enable carriage thereof upon the person, the weight of the tank or reservoir being imposed upon the shoulders of the operator as the straps 18 suspend said tank or reservoir therefrom.

Mounted interiorly ofthe tank or reservoir 1 at one side thereof is a bearing 19 while on the opposite side and exteriorly of said tank or reservoir is a bearing 20, the latter being formed with an externally threaded annular wall 21 providing a socket for the reception of a resilient washer 22 and a collar 23 integrally formed with a transverse shaft 24 mounted in said bearings 19 and 20. The externally threaded wall 21 has fitted thereon a removable cap 35 which surrounds the shaft 24 to retain the washer 22 against the collar 23 and thus afford a fluid tight joint between the bearing and said shaft 24, the shaft being formed with a crank handle 26 adjacent the cap for manual rotation of said shaft 24.

Carried by the shaft 24 interiorly of the tank or reservoir 1 is an agitator including a plurality of outwardly bowed sinuous shaped frames 27 joined at their ends with hubs 28 fixed to the shaft 24, the intermediate portions of the frames 27 being braced through the medium of a center spider 29 which is also fixed to the shaft. The agitator serves to stir the paint or coating fluid within the reservoir or tank 1 on rotating the shaft 24 by its handle 26 as will be obvious. The agitator acts to stir the paint in the tank to prevent the oil in said paint from rising to pump arranged exteriorly of the tank and having communication therewith through its top, a funnel-shaped spout protruding into the tank at the point of communication of saidpump therewith, a baflie ring interiorly of the tank spaced from its top, and means for causing agitation of the contents of the tank.

2. In a painting. apparatus, a tank, a pump arranged exteriorly of the tank and having communication therewith through its top, a funnel shaped spout protruding into the tank at the point of communication of said pump therewith, a baffle ring interiorly ofthe tank spaced from its top, means for causing agitation of the contents of the tank, and outlet means leading from the tank and having a cut off valve.

3. In a painting apparatus, a tank, a pump arranged exteriorly of the tank and having communication therewith through its top, a funnel shaped spout protruding into the tank at the point of communication of said pump therewith, a baffle ring interiorly of the tank spaced from its top, means for causing agitation of the contents of the tank, and outlet means leading from the tank and having a cut off valve, said tank having a hopper shaped bottom beneath the agitating means.

4. In a painting apparatus, a tank, a

pump arranged exteriorly of the tank and having communication therewith through its top, a funnel shaped spout protruding into the tank at the point of communication of said pump therewith, a baffie ring interiorly of the tank spaced from its top, means for causing agitation of the contents of the tank, outlet means leading from the tank and having a cut off valve, said tank having i a hopper shaped bottom beneath the agitat- 7 ing means, and a paint applying element having connection with the outlet means.

In testimony whereof I afliX my signature hereto.

ROBERT HAINSEY.
